The threshold voltage of a-Si: H/SiNx TFT will shift under long time gate bias stress  it is mostly leaded by charge trapping in gate insulator and defect creation in semiconductor. And it is hard to be applied in AMOLED for TFT because of its threshold voltage shift. In allusion to the phenomenon of charge trapping  a series of SiNx insulating films in different N/Si(0. 87 -1.68) ratio were deposited by PECVD in this paper  controlling different flow ratio of source gas SiH4 and NH3  and a great deal of tests (ellipsometer  infrared absorption (FTIR) and Electron Dispersion Spectrum (EDS) test ) were done on these samples. Based on these SiNx insulators  three different capacitance samples in MIS structure were done  degraded experiments and C-V tests on these samples were done. The C-V curve shift of capacitance which contained SiNx with slightly N-rich(N/Si is bigger slightly than 1. 33) was not evident before and after degradation  this result indicated that the defect density of this type SiN x was smaller  and could restrain charge chapping in the interface of a-Si:H/SiNx effectively. So that as gate insulator of TFT  SiN x with slightly N-rich could decrease the threshold voltage shift of TFT and enhance its stability effectively.
